In a preclinical study, the combination of Kisqali (ribociclib) and Afinitor (everolimus) treatment in a T-cell acute lymphoblastic leukemia cell line harboring wild-type RB1 and a NOTCH1 mutation resulted in decreased Rb1 phosphorylation and a greater inhibition of cell growth compared to either agent alone in culture (PMID: 28151717).

In a preclinical study, the combination of Kisqali (ribociclib) and Omnipred (prednisolone) resulted in a synergistic effect in a T-cell acute lymphoblastic leukemia cell line harboring wild-type RB1 and a NOTCH1 mutation in culture (PMID: 28151717).

In a preclinical study, the addition of Kisqali (ribociclib) to Purixan (mercaptopurine) resulted in an antagonistic effect in a T-cell acute lymphoblastic leukemia cell line harboring wild-type RB1 and a NOTCH1 mutation in culture (PMID: 28151717).

In a preclinical study, the addition of Kisqali (ribociclib) to Elspar (asparaginase) resulted in an antagonistic effect in a T-cell acute lymphoblastic leukemia cell line harboring wild-type RB1 and a NOTCH1 mutation in culture (PMID: 28151717).

In a preclinical study, the combination of Kisqali (ribociclib) and Adexone (dexamethasone) treatment in a T-cell acute lymphoblastic leukemia cell line harboring wild-type RB1 and a NOTCH1 mutation resulted in decreased cell viability and reduced phosphorylation of Rb1 in culture, and a greater survival benefit in xenograft models when compared to Kisqali (ribociclib) alone (PMID: 28151717).

In a preclinical study, the combination of Kisqali (ribociclib) and Velcade (bortezomib) resulted in an additive effect in a T-cell acute lymphoblastic leukemia cell line harboring wild-type RB1 and a NOTCH1 mutation in culture (PMID: 28151717).

In a preclinical study, the combination of Kisqali (ribociclib) and JQ1 resulted in an additive effect in a T-cell acute lymphoblastic leukemia cell line harboring wild-type RB1 and a NOTCH1 mutation in culture (PMID: 28151717).

In a preclinical study, the addition of Kisqali (ribociclib) to Methotrexate resulted in an antagonistic effect in a T-cell acute lymphoblastic leukemia cell line harboring wild-type RB1 and a NOTCH1 mutation in culture (PMID: 28151717).
